Programming Leftovers

• Eclipse OpenJ9 0.24 Released With A Ton Of Improvements - Phoronix

  In addition to Oracle's GraalVM 21.0 being released this week, the Eclipse Foundation has released OpenJ9 v0.24 as the newest feature release for their high performance JVM.

• The 10 most popular programming languages, according to Microsoft-owned GitHub [Ed: Why do some sites still reinforce the bogus idea that only projects that Microsoft controls using an oppressive and proprietary monopoly count or exist?]

• Carlos Garnacho: Threaded input adventures

  Mutter wasn’t always a self-contained compositor toolkit, in the past it used to rely on Clutter and Cogl libraries for all the benefits usually brought by toolkits: Being able to draw things on screen, and being able to receive input. In the rise of Wayland, that reliance on an external toolkit drove many of the design decisions around input management, usually involving adding support in the toolkit, and the necessary hooks so Mutter could use or modify the behavior. It was unavoidable that both sides were involved. Later on, Mutter merged its own copies of Clutter and Cogl, but the API barrier stayed essentially the same at first. Slowly over time, and still ongoing, we’ve been refactoring Mutter so all the code that talks to the underlying layers of your OS lives together in src/backends, taking this code away from Clutter and Cogl.

• Partially-Formed @ Meeting C++ 2021 talk is now online

  We will also show how developers that feel uneasy about the partially-formed state can avoid them at little to no cost, neither in code readability, nor performance, and use these examples to propose a new (or old) paradigm for API design: safe and unsafe functions (in the Sean Parent sense).

• How to implement a DevOps toolchain

  Organizations from all industries and of all sizes strive to deliver quality software solutions faster. This guarantees not only their survival but also success in the global marketplace. DevOps can help them chart an optimal course. DevOps is a system where different processes are supported by tools that work in a connected chain to deliver projects on time and at a lower cost.

First Look at OpenMandriva Lx 4.2 on the Raspberry Pi 4

When OpenMandriva announced the Release Candidate of OpenMandriva Lx 4.2 earlier this month, it revealed the fact that they finished the AArch64 (ARM 64-bit) port. That’s amazing news for OpenMandriva Lx fans who own an ARM64 device like the Raspberry Pi, Pinebook Pro, or even the PinePhone. The even better news is that OpenMandriva provided installable images for various popular devices, such as Raspberry Pi 3 Model B+, Raspberry Pi 4 Model B, Pinebook Pro, PinePhone, and Rock Pi 4C. A generic AArch64 image for UEFI compatible devices, such as various server boards, is also available for download.

Devices: Librem/Purism, Rockchip, and Axiomtek

• Reflashing the Librem 5

  Reflashing the Librem 5 is the best way to remove your personal data and put the phone back into factory defaults. Warning, this procedure will completely erase everything on the device! Make a backup beforehand! The Librem 5 gets reflashed from a separate 64-bit x86 computer running PureOS (or booted from the live PureOS disk).

• Getting Purism News – Purism

  We have a lot of irons in the fire at Purism whether it’s hardware development like the Librem 5, Librem 5 USA, or Librem 14, new products like the Librem Mini v2, or the wide range of software projects we maintain at https://source.puri.sm/. As a result, each week there is news on at least one of these fronts. We often get questions about the status of various projects, in particular from customers who are part of a crowdfunding campaign who want to know the answer to the all-important question: when will I get my device? In this post we will cover all the different ways you can stay up to date on Purism news.

• Rockchip RV1126 AI Camera SoC features 2.0 TOPS NPU, promises 250ms fast boot

  Rockchip RV1126 EVB V13 can help with evaluation and early development, but I could not find limited information includes a boot log showing it running Linux 4.9.111.

• PoE-enabled Apollo Lake system triggers machine vision

  Axiomtek’s compact “MVS100-323-FL” machine vision computer combines Apollo Lake with 3x GbE ports — 2x with PoE — plus lighting controls, trigger I/O, isolated DIO, and mini-PCIe. Axiomtek has previously launched vision I/O computers based on Intel’s 7th Gen Kaby Lake with products like the MVS900-511-FL, IPS962-512-PoE, and IPS960-511-PoE. The new MVS100-323-FL is a far more compact system with a slower, but more energy efficient Apollo Lake processor. [...] The MVS100-323-FL is powered by Intel’s quad-core x5-E3940, clocked at 1.6GHz. No OS support was listed, but Linux and Windows are almost certainly supported. Axiomtek’s AMS.AXView software is also available.
